is home to most of the microbes in your body, but your skin, mouth, lungs, and genitalia also harbour diverse populations. And as research continues into body biomes, it should reveal answers about how these microorganisms are promoting health or even disease.
What do humans and bacteria have in common?
A genetic code
, encoded into DNA usually runs every aspect of an organism’s life, either through directly producing proteins or by creating enzymes which regulate other chemical reactions. The genetic code is very nearly universal, and the vast majority of it is common to both bacteria and humans.
How are bacteria useful to us?

help to break down food and keep you healthy
